Executive Summary

This paper presents a new rate-less Coded Cooperation (CC) scheme for the two-user Cooperative Multiple Access Channel (CMAC), where two users cooperatively communicate with a common destination. The authors consider two rate-less CC strategies, a Fully Coded Cooperation (FCC) scheme used in the conventional rate-less cooperative schemes and a new Partially Coded Cooperation (PCC) scheme. In FCC, each user starts coded cooperation process only after the whole block of the other user's information symbols are fully recovered. In contrast, in PCC, each user starts cooperation as soon as it receives a fraction of new message sent from the other user.
